PIPES AND CHAMBERS
CULVERT PIPES A reliable solution for ditching, underpassing and rainwater drainage Culvert pipes are used to convey drain pipe water or rainwater under the ground. The smallest (110 mm) culvert pipes are used to convey rainwater falling on buildings from the rainwater chamber to the water chamber and for technical drain pipe systems around buildings. A wide range of different couplings and chambers is available for the 110 mm system, enabling the use of the product in a variety of environments. Larger culvert pipes are used as joint culverts or extensions of ditches. Culvert pipes can also be applied for other purposes, such as drain pipe inspection chambers or column moulds. The pipes are made of durable polyethylene, and their ring stiffness class is SN4 or SN8, depending on the application. The culvert pipes are twin-wall pipes with a corrugated outer surface and smooth inner surface. The twin-wall structure enables higher ring stiffness and a good flow rate without compromising the low weight that makes the culverts easy to handle. Technical data: Pipes in the SN4 strength class are suitable for applications with lighter loads, such as fields, private road junctions and yards and green areas. Pipes in the SN8 strength class are used in traffic areas, road construction and other applications with heavier loads. The selection of the strength class depends on the load, installation depth and earth material.

PRESSURE AND SEWER PIPES Pressure pipes are used as water pipes in conveying cold water, as pressure and gradient drains and in the tight-in-pipe renovation of old pipe systems. Traditional applications for pressure pipes include feed water lines in detached house construction, water and drain pipes in water co-operatives and municipal infrastructure as well as watering and irrigation pipes in agricultural applications. Pressure pipes are also used in various industrial applications. In addition to traditional applications, pressure pipes are now used in the increasingly popular geothermal heating systems, where the pipes are used to accumulate heat in systems based on ground, water and rock heat. We manufacture our pressure pipes in accordance with the EN 12201 standard.

WATER CHAMBERS Water chambers are used as branch chambers for drain pipe water and rainwater, in both areas covered by municipal infrastructure and at properties not covered by it. When rainwater and drain pipe water are conveyed into one discharge pipe, it must be ensured that rainwater cannot enter the drain pipe in the event of problems, causing the ground by the foundations to become wet instead of draining it. Water chambers are equipped with a ball float valve for this purpose. If the water level in the chamber rises due to a blockage or unusually heavy rainfall, the ball float valve blocks the inlet connection of the drain pipe and ensures that the drain pipe system works even in extreme conditions. The dimensioning of a water chamber is influenced by the size and roof area of the building. The roof area of a large building, such as a terraced house or an industrial building, collects a lot of rainwater, and a large amount of drain pipe water is collected around the foundations of the building. Due to this, the amount of water flowing through the water chamber is larger than for detached houses or holiday homes.

SEWER INSPECTION CHAMBER PACKAGE The sewer inspection chamber package can be used to combine intersecting sewer lines, with the chamber working as an inspection, service and branch chamber. The sewer inspection chamber packages have an intersecting PRO bottom element in which the bottoms of the inlet connections are at slightly different heights, enabling the inspection of the sewer line flow rates. The inspection chamber packages feature a telescopic pipe and cast-iron cover, so the chamber can also be installed on a vehicle route.

RAINWATER CHAMBERS Rainwater chambers are used to collect rainwater, storm water and melt water from the surface of the ground. The chambers are equipped with a cast-iron grating cover and a large sediment chamber, which prevents sand and other fine materials that pass through the grating from getting into the pipe system. The rainwater chambers have one discharge connection. In addition, the required number of inlet connections can be added to the chamber on the site using leadthrough seals.

SEWER INSPECTION PIPE PACKAGE The sewer inspection pipe package is used as an inspection and service pipe for a single sewer line. A straight sewer line must be equipped with inspection pipes at certain distances, so any clogging or breakage of the sewer line can be located and serviced.
